st: rank biserial correlation

dear all,
I would like to calculate a rank biserial correlation coefficient between dichotomous variables (e.g. application of a specific method in the aanalysis; yes/no) and ordinal variables (satisfaction with results of the analysis; five-point likert scale).
to my knowledge, rank biserial should do the job and can be fairly easy calculated in excel.
however, since I'd like to analyse the correlation between many, many different variables I would prefer an 'automatic' solution in stata rather than doing it manually in excel.
any idea?
thanks - any help it is highly appreciated!
best
martin
